COUNTERPATTERN USED IN THE MANUFACTURE OF TILES.

Application filed April 16, 1923. Serial No. (532,462.

To aZZ whom it may concern:

Be it known that I, ARTHUR HnNnoz, a citizen of the Kingdom of Belgium,and resident of Brussels, Belgium, have invented certain new and usefulImprovements in Counterpatterns Used in the Manufacture of Tiles; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters or figures of referencemarked therein, which form a part of this specification.

The present invention relates to counterpatterns used in the manufactureof tiles with encrusted designs made of sandstone, ceramic ware or otheranalogous materials.

In this process of manufacture, the separation in the stencil-frame ofthe different coloured materials composing the design, is regulated bycompartments which follow the lines of the design which it is desired tomake.

In order to regulate the admission of each colour which should fillcertain compartments and not others, there is applied each time on thestencil-frame a counter pattern, whose openings are arranged in such amanner as to coincide only with the particular compartments to be filledand which closes the other parts of the stencil.

Counter-patterns are known in which the openings for the passage of anyone colour have approximately the same area as the correspondingcompartments of the stencil which are thus left free and wide open.These counter-patterns have the serious disadvantage that at the pointswhere the stencil openings are relatively large, the colour isirregularly distributed.

Other counter-patterns are likewise known, in which the bottom wall isprovided with a series of openings of the same shape and size; suchconstruction present ing the objection that the openings are filleduniformly regardless of the shape of the stencil. In the small parts ofthe latter, these openings are useless and only complicate theconstruction of the counterpattern; and in certain cases, particularlywhen thick colours are used, or those which have a tendency toconglomerate, these openings become a hindrance in that they needlesslyimpede the delivery of the material.

To overcome these defects, and to permit a ready and uniformdistribution of the colour at the bottom of the mould, regardless of thecomplexity of the design, without obstructing any part of the colourpassages, the counter-pattern according to my invention is provided withopenings whose shapes and dimensions have three characteristics V 1. Atthe points where the area of the compartment is large, the circularopenings have relatively large diameters to enable the colour to fallfreely upon the bottom of openings will have a smaller diameter,

while still following the outline of the compartments, the area of theopenings being just sufficient to permit the passage of the heavymaterial therethrough.

The drawing accompanying the present specification represents for thesake of example one constructional form of the in vention.

Figure 1 is a View of the in plan, and

Figure 2 is a cross-section of Figure 1 on the line AB.

Figure 3 is a plan view of a partitioned stencil corresponding to thecounter'pattern shown, the compartments which should be filled with someone particular colour being shaded with dotted lines.

Figure 4 is a sectional perspective View, on line A-B, Figure 1, showingthe different parts in assembled relation.

In these drawings the pattern or stencil is constituted by a frame '1which is divided into different compartments 2 by thin vertical walls 3which follow all the outlines of the design.

countenpattern definite .3. At the points where the design has a Thecounter-pattern 4 is placed in this stencil, the two being held in theirrelative positions by the mould (not shown), in which the tile ismanufactured. The continuous edge 5 of the counter-pattern 41 rests onthe upper face of the mould.

The holes 6' of suitable shape are formed through the counter-pattern insuch a way as to allow the colour to pass across them.

in order to be emptied into the corresponding partitions 2 of thepattern.

The openings provided in the counterpattern have variable dimensions, soas to conform them to the size, shape and outline of the stencilcompartments. Hence, the passage of the colours is not hindered at'anypoint and their distribution takes place uniformly in thedifierentcompartments. The counter-pattern according to this construction hasopenings of greater diameter than is absolutely necessary to per-- mitthe passage of heavy material at the points where the compartments 2 (ligure 3) are located, so as to enable the colour to fall to the bottomof the mould withoutencountering the difficulties or obstructions to itsdistribution, the openings serving merely to guide and uniformlydistribute the material. I

On the other hand, at the points where the contours of thede sign areCOH'lPllCElttit, and where, for that reason, the distribution of thecolours is extremely difficult, the openings have a smaller diameterwhich conforms approximately to that absolutely necessary to allow theheavy material to pass and to feed it in sutficient quantity to thedifferent parts of the design.

In the" case of compartments such those indicatedat 2 which are of smallsize and, where there is no danger of unequal distributionof thecolouring material, the openings formed in the counter-pattern haveexactly the same shapeand size as. the compartments. i

It'goes without saying that the dimensions and shapes of the openings donot deeend solely upon the form of the design,

but equally upon thenatureheavy or thin of the colouring material.

Fig. 4c shows diagrammatically the elements specified above in workingposition.

in this figure, the counter-pattern 4 is placed on the work table 7 andmasks the stencil 1, blocking the compa 'tments of the latter which mustnot be filled, while leaving the colour entirely free to pass throughthe openings 6 in order to fall to the bot tom of the correspondingcompartments 2 and? of the stencil.

The improved counter-pattern can be used in any sort of process for themanufacture of ceramic tiles with encrusted designs, either by hand orby machine.

I claimas my invention:

1. In apparatus for the manufacture of ceramic tiles with encrusteddesigns in colour, the combination, with a stencil or pattern memberhaving partitions forming compartments torecelve material of differentcolours, of a counter-pattern whereon the colouring material isdeposited enibodying a plate formed with openings located directly abovesaid compartments; said openings being of three different typescomprising holes of relatively large diameter situated over compartmentsof coinparatively large area, elongated apertures situated overcomparatively narrow can partments and conforming exactly to the outlinethereof, and relatively small holes supplemental to the first-namedholes for filling in complicated areas of-the design.

In apparatus for the manufacture of ceramic tiles with encrusted designsin colour, the COlTlblDtltlOIl, with a stencil or patterninember havingpartitions forming compartn'ients to receive material of ditferentcolours, of a counter-pattern where on the colouring material isdeposited enibodyinga plate formed with openings located directly abovesaid compartments;

saidopenings comprising holes of relati ly large diameter situated overcompartments of comparatively large area, and relatively small holessupplemental to the first-named holes for filling in complicated areasof the design.

In testimony whereof I afl ix my signature in presence of two witnesses.
